CVE-2016-0701
Find out more about CVE-2016-0701 from the MITRE CVE dictionary dictionary and NIST NVD.
Statement
OpenSSL 1.0.2 provides support for generating X9.42 style parameter files. This feature does not exist in any previous versions of OpenSSL. Therefore versions of OpenSSL shipped with Red Hat Enterprise Linux 5, 6, and 7, and JBoss EAP and JBoss Web Server are not vulnerable to this security flaw.
Versions of OpenSSL shipped in Red Hat Enterprise Linux do not enable the SSL_OP_SINGLE_DH_USE option. However, most applications do not use SSL_CTX_set_tmp_dh()/SSL_set_tmp_dh(). Most of them use SSL_CTX_set_tmp_dh_callback()/SSL_set_tmp_dh_callback() without setting the key. This has the same effect as setting SSL_OP_SINGLE_DH_USE.
